I've been doing this in stages since my 20's.
First, I have snored all my life -- as did my Dad, Uncles, Grandfather, etc. They all got CPAP's later in life. I did my best to avoid it.
At 28, I had a turbinectomy. That's where they take a laser and burn the excess tissue in your nostrils to open those passages. Quick out-patient procedure. Did not hurt (after they coat your nose with something suspiciously like a liquid cocaine). Breathing was a little easier (at least that's what I told myself). Did not help the snoring all that much.
In my mid 30's I had the surgery -- complete roto-rooter -- tonsils, uvula, and adenoids. Hurt for about a week. Like swallowing glass or a really bad strep throat. But, after I healed, my wife says I was quiet as a baby -- for the first couple of years or so after the surgery.
Then, as I started to gain weight, the snoring came back. Not the apnea, but the snoring. Also noticed alot more problems with ear aches and sinus issues. You sinuses drain different after the surgery. If you are prone to sinus issues, you may want to think twice. These earaches HURT.'
Now, more than 10 years and 25 pounds heavier, the snoring is back, and so is the apnea.
I did another sleep study last year and finally relented and got the CPAP. Still hate that damn thing. Requires you to sleep on your back, which I have always disliked. At times you feel like your suffocating and at other times your walking into 50 mile an hour winds. I seem less rested when I use it than when I don't.
Personally, I think weight does have the most to do with it. If I were a skinny man who snored, I would get the surgery -- get rid of the excess tissue and get on with your life. But, having already exhausted all the options, my only real choice is to get used to a CPAP for the rest of my life or lose about 25 pounds see if I can get back to where I was right after the surgery.
For me, I am going to try the weight loss route. I really think that is the key. And if I am wrong, at least I'll look better after the weight loss and then I can resume using the CPAP. But, at least for me, all snoring/apnea treatments are a lose/lose proposition.
